Is there a downside to yokes like that?
-
• #5928
Compared to what?
I mean it is expensive to machine. There is wasted material (80% becomes swarf/chips) and time cycle per unit is quite a lot so they end up being expensive because quantity is also low.
Alternative is to do single sided yokes or a simpler flat bars style yokes.
I like flat bar yokez. But they are not always enough. If you compare my yoke design to eg. Cobra's sidewinder used on both ds and nds I think mine is the prettier solution.
But to achieve short stays with big tyres and relatively big chain rings while also keeping a certain aesthetic i think this is a cool solution.

Great minds think alike! Although I was joking...

I know this from experience. A while back I spent most of an afternoon MIG welding wearing gauntlets but with a T shirt on. Really prickly red arms for a few days after that.

Just compared to regular chainstay/ bb cluster. Right so the work to produce the yoke vs bending and dimpling chainstay tubing. I think yours looks cool and really clean, and very organic vs other yokes, but appreciate it's expensive for teh reasons you outline.

For most bikes dimpling is fine but 2.4" tyres and short chainstays mean you need a yoke

How short have you gone?
Sorry if I've missed that somewhere

I can't remember now. 425 I think.
But yoke is designed for 2.4" tyre, 420mm axle distance and 42t chainrings.
It's designed for the stayer gravel bikesEDIT: 428mm is the length I ended with

Last bits of rear triangle brazed up!
Now soak time and then braze ons and final sanding - then paint tests

I caught up on the last 10-or so pages and my conclusion is that you're still the best at what you do

That mega downtube is so hot

Thanks. It is a bit out of the normal. 44.5mm tandem downtube was all I could fine that was long enough.

Thank you all.
@BareNecessities I am afraid it will start out as 1x10 but late October it should become ss.

Yes. That's is my fave too. But I needed the space to mount a M5 bolt to work the chain tension and a straight tube gave me the smallest size possible will still having space for the bolt plus the bike being pretty porky I wanted to use as thin walled a tube as possible so opted for a bit of fancy seatstay cutoff instead of a thicker gauge that would allow me to bend it.
Thanks man. It was a bit of a concern actually. But it has come together nicely I think and it was piss easy to sand compared to clusters with single chainstays
